I am not sure if this is the correct forum so mods please move if appropriate:
I have available to me the following optical drives:
Lite-On LTR53527S CD Writer
Lite-On SHM165P6S DVD Writer
Benq EW164B USB2.0 DVD Writer
I have a large archive of media, mostly CDR80 (Verbatim and TY) and DVD+R/DVD-R (Verbatim, HP and TY) that I want to do some quality and transfer rate scanning on a random sample of disks and then test these disks every 6 months or so to try and keep a handle on the state of my media (Having been burnt by Ritek G05 in the past) I plan on using CD/DVD Speed to carry out the tests.
Unfortunately the EW164B will not do quality scans etc as the bridge chipset used by Benq (ALI I think) will not allow this and gives the infamous “Parameter Invalid” error. I am therefore left with by 2 Liteys and will use the SHM165P6S for DVD testing. My question is which should I use for CDR C1/C2 testing? The CD writer or the DVD writer. I have looked through various threads and have seen conflicting advice and in initial tests the C1 error levels I get from the same CDR on the different drives are significantly different.
I would be grateful for any advice from anyone who has done a lot of CDR testing. The other issue is one of what is an acceptable level of C1 errors on good (Verbatim or TY) media. I have been told elsewhere that:
C1 Max < 50
C1 Average < 10
C1 Total < 5000
Is a good benchmark. Does this seem reasonable ? I am OK with DVD testing having done lots of this and read the many interesting and informative threads on this matter. I have never doen any CDR testing so am not sure of what is good/bad or ugly
